Will OpenAI's valuation hit 2027 by December 31?

Market context

OpenAI’s private valuation would need to reach the listed threshold in Nasdaq Private Market data before 31 December 2026, and Polymarket is currently pricing that outcome at 6% YES. On the platform, the contract is bought and sold in USDC on Polygon, with outcomes represented by conditional tokens that settle against the NPM Price feed rather than a public exchange quote. That means the market is trading the probability of a reported private-mark valuation print, not the broader story around revenue, product launches or headline fundraising alone.

The latest comparable anchor point is OpenAI’s March 2026 funding round, when the company said it closed $122 billion of committed capital at a post-money valuation of $852 billion. Bloomberg reported the same figure in early April, and OpenAI’s own announcement confirmed the round and valuation. That leaves a wide gap to the threshold in any contract set above that level, but private-market prices can move quickly if there is another financing, tender, or NPM repricing. The current low probability suggests traders think another step-up before year-end is possible, but not the base case.

For the contract to resolve YES, a new NPM-published valuation has to meet or exceed the target on a trading day between market creation and 31 December 2026, with NPM data published on its usual one-business-day lag at 1:00 PM ET. Traders should watch for any further capital raise, employee liquidity event, or secondary pricing update that could feed into NPM’s methodology, as well as the timing of any disclosed closings or valuation updates. The settlement window can also extend into early January 2027 if relevant NPM business-day data has not yet been published by then.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
